Tuta Calendar Import

I’m trying to migrate from Proton to Tuta Calendar. I can export my Proton Calendar. When I press import in the Tuta (Android) app, it opens the .ics file and reads all the events, I then press import again and it tells me, “Could not reach server, it looks like you’re offline.” I am not offline, it’s clearly connected and events I input manually are syncing.

Does anyone know how to fix this?

Check your VPN or DNS or try Tuta support service.

Thank you!

I tried connecting over a regular WiFi connection with no VPN or DNS filtering and it’s giving the same error. Tuta doesn’t provide support on the free tier, which is the only reason I’m asking here.

If the import is failing, I’d first check the calendar file itself (usually .ics) and make sure it’s valid and not too large. Exporting a small test calendar and importing that can also help narrow down whether it’s the file or the import process causing the issue.
